Excitonic Energy Transfer in Red Algal Photosystem I Reveals an Evolutionary Bridge between Cyanobacteria and Plants
Mengyuan Cui, Zihui Liu, Miriam Izzo +9
Photosystem I converts light into chemical energy with near-unity quantum efficiency,yet its energy-transfer and charge-separation mechanisms remain debated. Evolution has diversif…
Coherent Dynamics of Charge Carriers in γ-InSe Revealed by Ultrafast Spectroscopy
Jianwei Shen, Jiayu Liang, Qixu Zhao +8
For highly efficient ultrathin solar cells, layered indium selenide (InSe), a van der Waals solid, has shown a great promise. In this paper, we study the coherent dynamics of charg…
Disentangling Dynamical Quantum Coherences in the Fenna-Matthews-Olson Complex
Hong-Guang Duan, Ajay Jha, Lipeng Chen +6
In the primary step of light-harvesting, the energy of a photon is captured in antenna chlorophyll as an exciton. Its efficient conversion to stored chemical potential occurs in th…
Photoinduced Vibrations Drive Ultrafast Structural Distortion in Lead Halide Perovskite
Hong-Guang Duan, Vandana Tiwari, Ajay Jha +9
Organic-inorganic perovskites have shown great promise towards their application in optoelectronics. The success of this class of material is dictated by the complex interplay betw…
Intermolecular Vibrations Drive Ultrafast Singlet Fission
Hong-Guang Duan, Ajay Jha 1, Xin Li +8
Singlet fission is a spin-allowed exciton multiplication process in organic semiconductors that converts one spin-singlet exciton to two triplet excitons. It offers the potential t…
Does electronic coherence enhance anticorrelated pigment vibrations under realistic conditions?
Hong-Guang Duan, Michael Thorwart, R. J. Dwayne Miller
The light-harvesting efficiency of a photoactive molecular complex is largely determined by the properties of its electronic quantum states. Those, in turn, are influenced by molec…
Nature does not rely on long-lived electronic quantum coherence for photosynthetic energy transfer
Hong-Guang Duan, Valentyn I. Prokhorenko, Richard Cogdell +4
During the first steps of photosynthesis, the energy of impinging solar photons is transformed into electronic excitation energy of the light-harvesting biomolecular complexes. The…
How two-dimensional brick layer J-aggregates differ from linear ones: excitonic properties and line broadening mechanisms
Arend G. Dijkstra, Hong-Guang Duan, Jasper Knoester +2
We study the excitonic coupling and homogeneous spectral line width of brick layer J-aggregate films. We begin by analysing the structural information revealed by the two-exciton s…
An efficient tool to calculate two-dimensional optical spectra for photoactive molecular complexes
Hong-Guang Duan, Arend G. Dijkstra, Peter Nalbach +1
We combine the coherent modified Redfield theory (CMRT) with the equation of motion-phase matching approach (PMA) to calculate two-dimensional photon echo spectra for photoactive m…
